DETAILED DESCRIPTION

This disclosure details an exemplary device and method for installing a latch module assembly into a vehicle door. An example embodiment of the latch module assembly and installation method are discussed in detail in reference to figures in the following description.

Although a specific component relationship is illustrated in the figures of this disclosure, the illustrations are not intended to limit this disclosure. In other words, the placement and orientation of the various components are shown schematically and could vary within the scope of this disclosure. In addition, the various figures accompanying this disclosure are not necessarily to scale, and some features may be exaggerated or minimized to show certain details of a particular component.

Referring to FIG. 1, a vehicle door 10 includes a latch module assembly 12 that includes a handle assembly 30 and a latch module 32 for securing the door 10 in a closed position. The door 10 includes an inner panel 14 and an outer panel 18. The relative terms inner and outer are with reference to a centerline of the vehicle such that portions nearer the centerline of the vehicle are “inner” relative those features and components that are further away from the centerline of the vehicle. Moreover, the door 10 may be any vehicle door, including front and rear doors as well as hatches or other structures that utilize a latch module assembly 12. An opening 16 is defined by a perimeter 24 formed as part of the inner pane. 14.

Referring to FIG. 2 with continued reference to FIG. 1, the example vehicle door 10 includes a first width 20 disposed about the opening 16 at the perimeter 24 that is smaller than a second width 22. The second width 22 is disposed between the outer panel 18 and the inner panel 14 away from the opening 16 in the location where the latch module assembly 12 is mounted to the door 10. Because the width 20 about the opening 16 is smaller than the width 22 within the door 10, the latch module assembly 12 can be difficult to assemble. The example disclosed latch module assembly 12 includes features for easing assembly and enabling installation through the smaller width 20 provided about the opening 16.

Referring to FIG. 3 with continued reference to FIGS. 1 and 2, the latch module assembly 12 includes a channel 26 that supports the handle assembly 30 and the latch module 32. The latch module 32 provides the mechanical coupling that secures the vehicle door 10 in a closed position. The handle assembly 30 is coupled to the latch module 32 through a mechanical link 34. The handle assembly 30 provides for actuation of the latch module 32 manually from an outer side of the door 10.

In this disclosed example, the latch module 32 includes the mechanical link 34 to the handle assembly 30 but also includes electrical features to provide for actuation of the latch module electronically. The channel 26 is securable to an interior portion of the vehicle door with fasteners, shown schematically in FIG. 9, that extend through several openings such as the opening 38 shown in FIG. 3. The handle assembly 30 also includes openings 36 for fasteners that are utilized for securing the handle assembly 32 as shown schematically in FIG. 9. Interior portions of the door 10 include features for securement of the handle assembly 30 once aligned and positioned within the door 10. The bracket 26 also includes features for securing window mechanism components and possibly providing a portion of a track for a window mounted within the vehicle door.

The handle assembly 30 is secured to a bracket 28 that is in turn mounted to the channel 26. The bracket 28 is secured to the channel 26 in a manner that enables movement of the handle assembly 30 between a collapsed position and an expanded position. In this example, the handle assembly 30 includes tabs 68 that are received within slots of the bracket 28.

Referring to FIGS. 4 and 5 with continued reference to FIG. 3, the example channel 26 includes a mount portion 40 with a first tab 42 including a ramped catch portion 44. The mount portion 40 also includes a catch 46 that includes a stop 48.

Referring to FIG. 5 with continued reference to FIG. 4, the example bracket 28 includes a first slot 50 that receives the first tab 42 and a second slot 52 that receives the catch 46. The bracket 28 includes a back 54 within which is defined the first slot 50 and the second slot 52. A top 56 is provided for mounting of the handle assembly 30.

The second slot 52 is elongated to receive the elongated catch 46. The catch 46 includes a top surface 45 on which the bracket 28 is substantially supported. The bracket 28 is loosely supported on the catch 46 such that the bracket 28 may slide back and forth on the catch 46. The first tab 42 constrains movement of the lower part of the back 54 such that the top 56 may move in a pivoting manner. Although the bracket 28 is supported on the channel 26 to enable relative movement, that movement is limited by the catch 46 and tab 42.

Referring to FIG. 6 with reference to FIGS. 3 and 5, the top 56 includes a mounting slots 58 and 60 and a locking member 62. The tabs 68 are received within the mounting slots 58 and 60 and held in place with the locking member 62. It should be appreciated that although an example mounting configuration of the handle assembly 30 to the bracket 28 is illustrated and described, other configurations and means of mounting the handle assembly 30 could be utilized and are within the contemplation of this disclosure.

Referring to FIG. 7, the example bracket 28 is shown mounted to the channel 26 and is movable on the first tab 42 and the catch 46 between the collapsed position indicted schematically by arrow 66 and an expanded position indicated schematically by arrow 64. In the collapsed position, a width of the handle assembly 30, bracket 28 and channel 26 are of a width that enables assembly into the vehicle door 10. Once installed within the vehicle door 10, the bracket 28 is movable along the channel 26 to allow the handle assembly 30 to move outward to the expanded position for fastening to the door 10.

Referring to FIGS. 8 and 9 with continued reference to FIGS. 2 and 7, in the collapsed position shown in FIG. 8, the bracket 28 is compressed to define a collapsed width 72. The collapsed width 72 includes the handle assembly 30, the bracket 28 and the channel 26. In the collapsed width 72, the handle assembly 30, bracket 28 and channel 26 are of a width that is less than the width 20 in the door 10 such that the latch module assembly 12 can be guided into the interior space between inner panel 14 and outer panel 18 without obstruction and with sufficient clearance to ease assembly.

Referring to FIG. 9, the latch module assembly 12 is shown in an expanded or installed position where the handle assembly 30, bracket 28 and channel 26 are expanded to the expanded width 74. The installed width 74 is greater than the collapsed width 72 and provides for positioning of the handle assembly 30 within a width 22 of the door 10 that corresponds with the installed position. The bracket 28 is movable on the tab 42 and catch 46 to enable expansion between the collapsed and expanded widths 72, 74. The movement of the bracket 28 is not immovably fixed to the channel 26. Instead, the bracket 28 is movable relative to the channel 26 and limited by the catch portion 44 of the first tab 42 and the stop 48 of the catch 46.

Once in the assembled position shown in FIG. 9, fasteners 35 are extended through openings 36 to secure the handle assembly 30 in place. The bracket 28 no longer is relied on to support the handle assembly 30. The attachment of the fasteners 35 is shown schematically and it should be understood that the door 10 will include locations for mounting the handle assembly 30 as required to enable access and operation. Additionally, the channel 26 is secured to a portion of the door schematically shown at 15 by fastener 39 inserted through opening 38. The portion 15 within the door 10 is tailored to each specific door shape, size and configuration that are all within the contemplation of this disclosure.

The handle assembly 30 is biased outward toward the expanded position by structures such as the mechanical link 34. Accordingly, compression to the collapsed condition 66 requires application of some force to both move and hold the handle assembly 30 in the position shown in FIG. 8. Once the force is removed, the handle assembly 30 moves at least partially toward the expanded position 64 shown in FIG. 9.

Referring to FIG. 10 with continued reference to FIGS. 8 and 9, an example method of assembling the latch assembly 12 into the vehicle door 10 includes a first step of collapsing the handle assembly 30 and bracket 28 into the collapsed position 66 as is shown in FIG. 8. In the collapsed position 66, the latch module assembly 12 is guided into the door 10 as is schematically indicated by arrow 70. The door 10 includes the opening 16 with the perimeter 24 about the opening 16 that defines the width 20 (FIG. 2) that is smaller than the desired installation width but larger than the collapsed width 72 of the latch module assembly 12. Accordingly, in the collapsed position 66, the latch module assembly 12 has sufficient clearance to enable efficient guiding through the opening 16 into the interior space of the door 10.

Once the latch module assembly 12 has been guided into the door, the channel 26 is secured within the door 10 utilizing fasteners 39 or other attachment devices as may be utilized and understood by those skilled in the art. A window and or portion of a window operating mechanism schematically shown at 76 may be attached to or supported on the channel 26 once installed within the door 10.

Referring to FIG. 11 with continued reference to FIGS. 8, 9 and 10, once the channel 26 has been secured into the door 10, the handle assembly 30 is expanded outwardly to the expanded installed position 64 to the extended width 74. In the expanded position the handle assembly 30 is secured to the door 10 with fasteners 35 as shown schematically in FIG. 9. The bracket 28 is not mounted or fixedly secured to the channel 26 and enabled to move freely to allow adjustment of a position of the handle assembly 30 for securement within the vehicle door 10.

Accordingly, the disclosed example bracket 28 and channel 26 connection enable the latch module assembly to be collapsed into a condition that enables assembly into smaller opening sizes while maintaining a desired orientation and greater width once assembled into a door.
